Fermentation Temp Range
Each yeast strain has a temperature range where it performs best. Lagers require cooler temps, while Kveik yeasts can ferment in extreme heat. Maintaining the proper fermentation temperature for each yeast strain is crucial its health. Matching a yeast's ideal range to your environment (or your ability to control temp) is key to getting clean, consistent results.
Scale from 30°-120°F

WLP001 California Ale Dry Yeast is White Labs' flagship American ale strain, developed to produce clean, neutral fermentations that allow hop and malt flavors to remain the primary focus. Its restrained ester profile makes it one of the most versatile yeast strains available for modern homebrewing.

With an attenuation range of 75–85% and medium flocculation, WLP001 creates crisp, well-balanced beers with excellent drinkability. The strain ferments cleanly across its recommended temperature range of 68–73°F (20–23°C) while producing minimal yeast-derived character.

The dry format delivers the same dependable performance associated with the original WLP001 liquid culture while providing improved shelf stability and convenient direct pitching. It performs consistently in standard-strength beers as well as higher-gravity recipes with proper fermentation practices.

Whether brewing hop-forward IPAs, classic American pale ales, robust porters, or clean stouts, WLP001 produces reliable, repeatable fermentations that highlight recipe ingredients instead of yeast character.
